In liberal schools of economics, autarky is usually considered from the perspectives of economic trade protectionism, closed economies, and threats to welfare. Nevertheless, the concept of autarky has gained a new meaning, understood as the local utilization of renewable energy resources from the perspective of their inter- and intragenerational distribution. Local action is shaped by the global perspective. This research consists of three steps. First, a model of energy autarky has been offered based on the system theory. The model shows the variety of the structures and features of energy systems offered in today’s debates on energy autarky. Second, the key postulates of sustainable development have been presented to define an autarkical sustainable energy system. Finally, the concept of bioenergy villages in Germany has been presented to illustrate the approach to energy autarky. The research shows that the concept of autarky and single solutions, such as the use of renewable resources, are not themselves a success from the perspective of sustainable development; this misunderstanding is well illustrated by the evolution of the German concept of bioenergy villages into smart villages. Keywords: energy autarky model; energy policy; renewables; economic equilibrium of autarkical systems; absolute and relative autarky 1. Introduction The idea of an autarky has a long history and many facets. There have been fierce economic and political debates on autarky, even in recent history, leading to the negation and unpopularity of this idea. The present policy follows the concept of sustainable development, where it has gained a new meaning as the local utilization of renewable energy resources from the perspective of their inter- and intragenerational distribution; local action is shaped by the global perspective. In liberal schools of economics (i.e., classical or neoclassical), autarky is usually considered from the perspectives of economic trade protectionism, closed economies, and threats to welfare [1–3]. Moreover, the term was vastly developed by the planners of centralized economies in Germany and socialistic countries [4–6]. These analyses usually pointed out the economic inefficiency and authoritarianism (autarchy) of these economic and social orders. Therefore, the concept of autarky in terms of freedom, paradoxically has a bad reputation in liberal economics. The remarkable economic doctrine in the light of economic protectionism was mercantilism. The economic view, which was particularly well developed from the sixteenth to the eighteenth century, was that economic power is achievable through gold and silver stocks. An unequal balance of trade was a remedy for both full employment and bullion (gold and silver) accumulation. Various means of Sustainability 2019, 11, 4996; doi:10.3390/su11184996 www.mdpi.com/journal/sustainability Sustainability 2019, 11, 4996 2 of 14 protecting economies became popular, such as custom duties or other legal regulations of economic exchange between countries, usually pictured by the example of the Navigation Acts in England originally adopted in 1651 [7,8]. However, the concept of energy autarky related to the idea of sustainable development has different origins from the liberal economic debate. Today’s discussion is often linked with the idea of sustainable development. Since local activity refers to global thinking, energy autarky is driven by transnational policy recommendations and agreements [9–11] that originated from socio-economic and ecological concerns and the global perspective of just human development. In particular, the Cocoyoc Declaration produced by the members of a symposium organized by the UNEP (the United Nations Environment Programme) and UNCTAD (the United Nations Conference on Trade and Development), Patterns of Resource Use, Environment, and Development Strategies, was eminent in this field [12]. The idea of sustainability was presented in terms of self-reliance as being dissimilar to autarky: “It implies mutual benefits from trade and cooperation and a fairer redistribution of resources satisfying the basic needs. It does mean self-confidence, reliance primarily on one’s own resources, human and natural, and the capacity for autonomous goal-setting and decision-making. [ ::: I]t implies decentralization of the world economy [ ::: , and] it also implies increased international co-operation for collective self-reliance” [13] (pp. 897 898). Future documents − on sustainable development policy, for example Agenda 21, utilized the terms “self-sufficiency” and “self-reliance” interchangeably [14] (for example, Articles 32.5.d, 3.8.l, 14.16, 14.26, or 14.93), but it is a rather semantic interpolation to separate this view from the negative connotations and associations of the term “autarky” in political and social sciences. Self-reliance is perceived as an element of the global climate mitigation policy and the way of allocating social, economic, and natural resources from the inter- and intragenerational perspectives. Müller et al. [15], referring to the original definition of sustainable development presented in the Brundtland Report in 1987, defined a sustainable energy system as follows: “it must be capable of providing the energy services demanded by the current population, whilst ensuring that future generations find the economic, social and ecological resources they require” [15] (p. 5800). This postulates the criteria for the evaluation of the final outcomes of the action that should be undertaken toward achieving energy sustainability. The practical implications are the ongoing processes of transformation and the examination of different solutions. The ideas of self-reliance and self-sufficiency presented in this document were included in the action plan for the upcoming summit. Agenda 21, as a plan of action for the twenty-first century, was implemented during the UN World Summit in 1992. This detailed document of action widely utilized the ideas of self-reliance and self-sufficiency. The self-sufficiency strategy, as a sustainable method of energy production, was articulated in Chapters 14 (Article 14.16 or 14.93) and 32 (Article 32.5), respectively, on promoting sustainable agriculture and regional development and strengthening the role of farmers [14]; these were mostly related to farming and rural areas. The postulates of energy efficiency, universal access to energy, and the role of renewable energy resources in sustainable development were also articulated in Chapter 4 on changing consumption patterns [14]. The UN World Summit generally reaffirmed the above postulates [16] and reformulated them in a new document named “The Future We Want” [17]. Finally,the 2030 Agenda for Sustainable Development by the United Nations from 2015 presented them in the form of 17 Millennium Development Goals and 169 targets [18]. It emphasized that the goals are “integrated, indivisible and balance the three dimensions of sustainable development: the economic, social and environmental” [18] (p. 1). The energy issues were postulated within the seventh goal, entitled “Ensure access to affordable, reliable, sustainable and modern energy for all” [18]. This goal was further developed into the three following strategies: (1) universal access to modern energy services, (2) the improvement of energy efficiency, and (3) the increased use of renewable sources [19]. The socio-political postulates predominate in the first strategy, which refers to inter- and intergenerational just energy distribution. The next one mirrors the economic dimension, while the third is mostly concerned with environmental Sustainability 2019, 11, 4996 3 of 14 issues. According to the concept of sustainable development, an energy village has to implement all these strategies simultaneously. The new documents published since 2012 did not use the terms “self-sufficiency” or “self-reliance” (or “autarky”) directly, although “The Future We Want” refers to the guidelines of the Food and Agriculture Organization of the United Nations in Article 168 on the institutional framework of sustainable development. The latter coined the concept of energy use in terms of “energy-smart” farming linked to the model of integrated food–energy systems (IFESs) [20], “in which food and energy are produced concomitantly on farms to achieve sustainable crop intensification” [20] (p. 35). The concept is mostly related to bioenergy, that is, energy from biomass generated from agriculture, and assumes only varied degrees of energy self-sufficiency on small farms. Nevertheless, the energy self-sufficiency in the context of all renewable energy sources is seen as a sustainable energy-smart strategy for local communities or small farms; it also emphasizes additional revenues from the potential energy excesses if the on-site demand is met [21].
